Putting My Foot In My Mouth

This evening my girl and I went out on a date (my idea, taking the lead), and I was trying to follow the 3H's (hangout, have fun, hookup) and PCP (playful, charming, positive). Everything was going great, flirting, kissing, physical contact, escalation, etc.

She commented on something that caused me to comment on all the different pretty girls in the restaurant/bar. She then mentioned "seeing" different women, and I know that "seeing" to her means sex / dating, of course, but I was trying to keep it fun and playful. I joked that "Oh, yeah, I'm 'seeing' so many girls. The benefits of having two eyes." This caused her to visibly close up and get distant. I should've backed off or switched the subject, but I dug myself in deeper trying to be playful. "Oh, but don't worry, you're the one I'll be 'seeing' the most. I won't even call them that much." She replied, "Oh, you just keep digging that hole you're in." And I responded, again trying to be playful, "I wonder if I keep going whether I'll come out the other side."

Then I made the mistake of joking that me and a buddy were going to the local university to practice getting numbers and talking to chicks (that was our plan, he needs the practice more than myself, but it wasn't like I was trying to pick them up and cheat on her). She did not like that at all and her body language reflected that.

We left but she was visibly upset. I let her have her space as we walked and tried not to be phased by it, talking very much less but keeping my comments light and casual. I took her home, didn't turn off the car or unbuckle my seat belt, as I already assumed I wasn't getting invited in. (Maybe a mistake?) She started tearing up, said she was upset, and told me that I keep mentioning things that make her feel like I'm actively pursuing different women. (I'm not.) She said she thought we were seeing each other. (We are, I don't want to change that.) She told me she feels like I'm just using her as practice and as a stepping-stone. (I'm not, I'm trying to learn and grow with her.) She said I keep bringing up "the end of us." (No idea where she got this from, but apparently she thinks I'm not committed?) I told her no, that wasn't true, she was wrong, has the wrong idea, etc. and said I'm sorry she feels that way and that I'm sorry I gave her that impression.

She told me that she'd call me later and I have resisted the urge to contact her thus far. (Best to give her time and space, supposedly.) The irony in all this is that she's the 2nd girl I've ever had sex with, and the only girl I've actually dated, but she seems to get the impression that I'm a 'player' or that she's a booty call or that I've got a dozen girls lined up in the wings. (All her assumptions from comments I intended to be playful said in the past: "You going to leave me hard and dry tonight?", for example; or saying that I need and want "more practice" to get my stamina up (talking about sex, with her, obviously) and how she could be "one of my French girls," (I paint and most of my subjects are real girls whose permission I have to draw nude.) We've been seeing each other for about 7 weeks now regularly every weekend, and she applied the "we're dating" and "we're exclusive" labels to us, but this fuckup of mine got me feeling like I needed to vent.

The thought of porn and rubbing one out crossed my mind, but I refused, so I came here instead. This probably should be in my journal instead of a thread unto itself, but I wanted thoughts and criticisms and advice, not that any of it will make me feel any better.
